基于虚拟域动态逆的空地反辐射导弹轨迹优化
Trajectory Optimization for Air-to-ground ARM Based on Inverse Dynamics in the Virtual Domain
摘要
Abstract
Aiming at the countermeasure against radar switching-off of anti-radiation missile,a trajectory optimization algorithm was designed based on the method of inverse dynamics in virtual domain( IDVD) . Based on the inverse dynamics principle,the position of missile was fitted by virtual arc,and the boundary conditions and state variables were transformed from time domain to virtual domain. The derivatives of boundary conditions were derived in virtual domain. The trajectory was discretized according to the direct method,and the performance indexes were set by penalty function to obtain the optimal trajectory. The simulation results show that the trajectory of anti-radiation missile generates rapidly by using this method. The purpose of hitting the target precisely with the radar of target switching-off was realized. This method can solve the high order derivatives of boundary conditions conveniently by virtualizing the length of trajectory,which simplifies the calculation process,and the reference trajectory can generate rapidly,and it is also insensitive to the initial value of parameters.关键词
